invention consists in the wet conveyer sys-- tem hereinafter described, and I particularly defined in the claim. H.

i In the accompanying drawings illustrating the present invention, Fig. 1 is a'plan xof a'wet conveyer system; Fig. 2 is an elevation thereof; Fig.-3-is aI-detail of the nozzle; Fig. 1-is an end elevation of a fan casing; Fig. 5 is a side elevation thereof; Fig. 6 is a sectional elevation of the fan; and Fig. 7 is a front elevation of the fan employed in the system.

The illustrated embodiment of the invention is described as follows: An extractor fan 10 is connected by means of piping 11 with a series of switches 12. From each switch a side pipe 13 extends to a nozzle 14. Each side pipe and the end of the pipe 11 provided with its nozzle, is arranged in convenient position with relation to a bin or receptacle from which wet materials are to be carried away. Thus, each nozzle is located near a dye machine 15. The switches are so arranged that only one of the nozzles is in use at any given time. Thus, when the switch nearest the fan is in use, the switch member 12 connects the pipe 13 with the conveyer pipe 11, and suction is exerted upon the nozzle 14 of the first dye machine. and only on that nozzle. The extractor fan 10 receives the materials brought to it by the conveyer pipe 11 through the short expanding connection which discharges into the eye of the fan. This expanding or tapering connection between the pipe 11 and the eye of the fan slows up the velocity of the entering air and material so that the latter does not impinge upon the fan with the severity with which it would if the taper were omitted. The fan discharges the materials through the discharge conveyer pipe 16 to an arrester 17. This arrester comprises a generally conical shell into of the arrester. s'queezer hopper 18.

jwhich the discharge conveyer pipe 16 delivers .the materials tangentially so that the -materials whirl around the exteriorof the drum-of the arrester and drop out through 60 .the open bottom, while the air which has .beenemployed in carrying the materials to the arrester .is discharged through the top The materials drop into a The extractor fan casing illustrated in -Fig. is a strong, heavy fan casing provided ;with=two heavy bearings 20. for supporting the fan shaft and fan, the fan being mounted on -the end of the shaft which projects into jthevi'nterior of the casing 10. The fan itself comprises a.h'ub 21, having angle bararms 22 cast in place in the hub,'to which .the .blades;23 fiof thefan are secured in the I1sual'-Inanner.'-- The-right-hand side of the fan, as.sl1own'-in=-Fig.;6,'is the side toward -.=the. Bye-2 L? of: the fan into which the material carried by the conveyor pipe is discharged. This fan is provided with a back plate 25, against which the materials may strike as they enter the fan, and as the fan rotates it carries the materials around with it and they are thrown out through the mouth 26 of the casing. It is to be noticed that the edges of the fan blades which are on the side toward the eye of the casing are rounded off so that no portions thereof will engage and hold any materials entering through the eye.

The nozzle 14 is of special construction. It has a nozzle tip 30 which is reinforced with a ring 31 at its end, and it may be raised and lowered by means of a flexible cable 32. This nozzle tip 30 is received in the lower end of a taper pipe 33, mounted on the end of the side pipe 13. This taper pipe is provided with four angle iron guides 84:, inside of which the nozzle tip slides. These guides 3& hold the nozzle tip centered with relation to the lower end 35 of the taper pipe 33. lVhen wet material is being presented to the mouth 36 of the nozzle tip, in case the whole month should be blocked, air will still be permitted to enter the side pipe 13 through the openings 37 between the guides 34, so that a supply of air will still be afforded to the side pipe and the conveyer pipe, even when the mouth of the nozzle is choked. If this provision were not made it is apparent that the cessation of flow of air in the conveyer pipes would permit the materials being carried thereby to fall, and

a general break-clown of the system might ensue; But with this provision for added air supply in case of choking the mouth of the nozzles, no such contingency is possible. i

Let it be assumed that it is desired to lift wet wool from the right-hand dye machine 15. All the switches 12 will be turned so as to make a straight run in the conveyer pipe 11 through the switches from the end dye machine. Then the end nozzle of the pipe will be swung and dropped into the dye machine, and the material therein presented to the nozzle, and the draft created by the extractor fan will lift the material presented to the nozzle mouth and carry it through the extractor fan and discharge it convenient method of arranging the suctionline so that the material may be delivered to it at a. plurality of points, as at the several dye machines as shown.

' The fan is a stron hi h SJBGCl heav Cl C) y suction fan which creates vacuum of 15 to 18 inches of water, and thereby secures great lifting power at the nozzles, and the higher velocity of the air acts -.to transport the Wet materials through the system Without difficulty. Curved edges on the intake side of the fan revent any catching of the fan upon the goo 5 being delivered to the fan blades, and thereby prevent any accidental clogging of the fan by the materials passing through it. I

Any form of arrester may be used; thus, the well-known condenser may be employed, if desired, where conditions would indicate its use in place of an arrester of the form shown in the drawings, whichiis, in general, of the same general type of COIlStTllCtlOIlfiIld operation as the well-known Allington and Curtis dust collector;

Having thus described'tlie invention, What .IS claimed 1's:

A wet conveyer system comprising a eonveyer pipe provided at itsend withza 'plurality of separated nozzletip guides,"and"a telescoping nozzle tip 'supported'in the end of the conveyor pipe and held an positionby the guides which form passageways between the In testimony whereof I have signed;
